2 Claims. (Cl. 271-83) This invention relates to new and useful improvements in fly sticks for printing presses.

More particularly, the present invention proposes the construction of an improved metal fly stick for printing presses which can be quickly and securely mounted on the fly shaft of a printing press to handle paper at high printing speeds in an eflicient and economical manner.

As a further object, the present invention proposes forming the metal fly stick so that it will be adjustable to a number of various predetermined lengths.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a side view of a metal fly stick constructed and arranged in accordance with the present invention.

Fig. 2 is a top plan view of the stick shown in Fig. 1.

Fig. 3 is a perspective diagrammatic view with parts .broken away of a printing press with a plurality of the fly sticks shown in Figs. 1 and 2.

Fig. 4 is a longitudinal sectional view of the fly stick shown in Figs. 1, 2 and 3 with parts broken away.

Pig. 5 is a perspective view similar to Fig. 4.

Fig. 6 is a perspective view of the connecting block shown in Figs. 4 and 5.

Fig. 7 is an end view of the block shown in Fig. 6 with the rod indicated in dot-dash outline on it.

Fig. 8 is a view similar to Fig. 5 but illustrating a modification of the present invention.

Fig. 9 is a sectional view taken on line 9-9 of Fig. 8.

Fig. 10 is a sectional view taken on line 1010 of Fig. 8.

Fig. 11 is a fragmentary view similar to Fig. 8 but showing the stick extended to a predetermined length.

Referring more particularly to the drawings, the metal fly stick of the present invention, in accordance with the first form of the invention illustrated in Figs. 1 to 7, inclusive, has a metal rod 15 and a connecting block 16.

Metal rod 15 has a hollow rectangular connecting rod end 17 with a flat upper surface 18 and spaced fiat sides 19 and 2%. Two spaced screw or bolt holes or openings 21 are provided in the upper surface 18 extending therethrough.

Metal rod 15 also has a hollow tapering closed free end 22 and a hollow substantially inverted V-shaped cross section shank 23 extends between the ends 17 and 22.

Connecting block 16 also is of metal and frictionally fits in the hollow rectangular connecting rod end 17 of rod 15. Block 16 has one end 24 with upper tapered edge rates Patent 0 ice portions 25 and 26 and a flat upper surface 27 with spaced threaded screw openings 28 adapted to align with the screw openings 21 through the upper surface 18 of the end 17 of rod 15 when the block 16 is in the end 17.

A plurality of fly stick rods 15 and connecting blocks 16 are mounted on a fly shaft 29 (Fig. 3) of a printing press 30 by clamps 31 to form the fly of the printing press.

The modification of the invention illustrated in Figs. 8, 9, 10 and 11 is characterized by the provision of a fly stick metal rod 35 having a hollow rectangular connecting rod end 36, a hollow tapering closed free end 37 and a hollow substantially inverted V-shaped shank 38 which is in two sections 39 and 40. A connecting block 41 fits in the end 36 of rod 35 to connect the rod to a printing press fly shaft. A connector bar 42 frictionally fits in the sections 39 and 4t) spanning the sections and holding them in alignment. The rod 35 can .be made any predetermined length within the limit of the connector bar 41.

While we have illustrated and described the preferred embodiments of our invention, it is to be understood that we do not limit ourselves to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.

Having thus described our invention, what we claim as new, and desire to secure by United States Letters Patent 1s:

1. A metal fly stick for printing presses comprising a metal rod having a hollow rectangular connecting rod end and a hollow tapering closed free end with a hollow substantially inverted V-shaped shank between said ends, said shank having a tapered portion adjacent said rectangular end, and a connecting block adapted to fit in said hollow rectangular connecting rod end for connecting said rod to a fly shaft clamp, said connecting block being a metal rectangular block with one end having upper tapered edge portions for fitting into the tapered portion of the shank, said hollow rectangular connecting rod end of the rod having a flat upper surface with spaced screw openings and said connecting block having spaced threaded screw open-' ings adapted to align with the screw openings in the upper surface of the hollow rectangular connecting rod end of the rod.

2. A metal fly stick for printing presses comprising a metal rod having a hollow rectangular connecting rod end and a hollow tapering closed free end with a hollow substantially inverted V-shaped shank between said ends, and a connecting block adapted to fit in said hollow rectangular connecting rod end for connecting said rod to a fly shaft clamp, said connecting block also being of metal and frictionally fitting in said hollow rectangular connecting rod end of the rod, said hollow rectangular connecting rod end of the rod having a flat upper surface with spaced screw openings and said connecting block having spaced threaded screw openings adapted to align with the screw openings in the upper surface of the hollow rectangular connecting rod end of the rod, said shank being in two sections and a connector bar adapted frictionally to fit in adjacent ends of said sections and hold the sections in alignment.
